Specification of Letters Patent.

Application filed December 7, 1907. Serial No. 405,618.

I T call whom it may concern:

Be it known that I, Lucius TINSLEY, of Crawfordsville, in the county ofMontgomery,

State of Indiana, have invented certain new for Electrical onductors, ofwhich the following is a specification.

This invention contemplates certain new and useful improvements in wallbrackets .for

. ter with grooves 14 formed in the top I View on line 44, Fig. 1.

electric conductors and relates more particularly to that class ofinventions known as divided insulators for holding or supportingelectric wires. 1

The invention'has for its object the production of a simple and improvedclamp adapted to support a plurality of conductors, such as the twistedwires used in telephone drops in residences or on pole tops, orsuchother places where such devices are found convenient.

'A further object is to provide means for insuring that the conductorwires willremain separated at all times, and thus avoid danger of shortcircuiting.

I A further object is to provide improved means for securing the bracketin position and for simultaneously clamping the members of the insulatortogether.

The invention will be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawing:Figure 1 is a plan view illustrating myinvention. Fig. 2 is a side elevation thereof. Fig. 3 is an end View.Fig. 4 is a transverse sectional Fig. 5 is a bottom plan view of the tosection of the insulator] Referring to the rawing, 10 designates the topor outer member and 11 indicates the lower member of my improvedinsulator. The under face of member 10 is provided with transverseroughened grooves 12 flared at the ends, as indicated at 13 and adaptedto regisface of member 11. Said members are also provided in their endswith registering grooves 15. The clamping member comprises a base orflange 16 provided with a central opening 17 conforming to the contourof the members 10, 11, said opening being spanned by a yoke 18. Saidyoke is widened centrally at 19, and fits within a corresponding shapedgroove or recess 20 formed in the outer face of member 10. Said yoke isalso widened or thickened, as indicated at 21 to i i i and useful Irnrovements in Wall-Brackets l 1 currents.

fit in the grooves 15. The base 16 is also provided with openings 22 forscrews or other securln g means.

are p aced between members or blocks 10, 11, resting in the grooves 12and 14, after which the clamping member is passed over said members,bein threaded over the 'ends of the wire. nwill be observed that theblock 11 projects through'the openin 17 in the base which purpose. Theclamping member is then secured in position against the wall or othersupport. When the parts are assembled the portions 19 of the yoke 18 litin the grooves 15 to prevent lateral movement oi the blocks 10, 1 1, andthe outer arm of said yoke enters the recess 21, whereby longitudinalplay is prevented. As the base member 11 bears against the wall or othersupport the flange 16 is held away from the latter, with the resuit thatmembers 10, 11 are firmly clamped against the wires or conductors as thesecuring screws are driven home. It will alsobc observed that thebracket or yoke may be enameled or covered with avitreous coating toafford a maximum insulation when my device is used to support wirescarrying heavy 1 claim as my invention? 1 1. A wall bracket comprising aplurality of insulating members, and a clamping-member having a basesurrounding the sides of one of said insulating members and rovided witha yoke extended over the top 0 the other insulating member.

2. A wall bracket comprising inner and outer insulating members, and aclamping member having a base surrounding the sides of the inner memberand provided with a yoke extended over the top of said. outer membersaid clampin member being also provided with means or engaging the endsof said insulating members to prevent lateral movement thereof.-

3. A wall bracket comprising inner andouter insulating members eachprovided witlf end grooves, and a'clamping member sur rounding saidinner insulating member and embracing the top of the outer insulatingmember, said yoke being thickened to fit in said grooves. y

4. A wall bracket comprising inner and outer insulating members, theouter face-of said outer member being provided with-a longitudinalgroove orrecess, and aclarnping member having a base surrounding thesides In practice, the wires or other conductors '65 permits sufficientplay For this lot vvide with a longitudinal groove or recess,

ofthe inner insulatin member and provided l with a yoke arrange to fitin said roove or A recess, said yoke'extending over t e top of the outermember.

' 5. A wall bracket comprising inner and outer insulatin members eachprovided with end rooves, lie outer member being proand a clampingmember surrounding the inner insulating member and provided with a iyoke arranged to fit within said longitudinal groove or recess, saidyokealso having thickened portions to fit said end grooves.

6. A wall bracket comprising inner and outer insulatin members, and aclamping member forme with a securing flange surrounding said innermember andprovided with a yoke passed over the outer f ace of the outerinsulating member.

7. A'wall bracket comprising inner and outer insulatin members, and aclamping member forme of a base-having'an openin l to receive said innermember, and provide l with a yoke spanning said opening and passed overthe outer insulating member.

' 8. wall bracket comprising inner and outer msulating members, and aclamping member, said clamping member embracing the sides of the innermember and provided with means for preventing lateral and longitudinalmovement ofboth of said insulatmg members.

9. A wall bracket comprising inner and outer insulating members, and aclamping member formed with a yoke having an enlarged portion engagingthe outer face of the outer insulator, said outer insulator beinggrooved to receive said yoke.

10. A wall bracket comprising inner and outer insulating members eachprovided with end grooves, the outer member being also provided with alongitudinal groove or recess, and a clamping member provided with abase having an opening to receive the inner insulating member, and alsohaving a yoke 1 engaging said grooves and said recess.
